Restore QSPanelControllerBase listening state

In flexiglass, when the views are detached we set the
tile layout to be not listening. However, if we were listening before,
we should still be listening after re-attaching. This makes sure that
that is restored properly.

Note that this applies to both QQS and QS (as they both use the same
abstract controller class).
